Choose the equation below that represents the line that passes through the point (2, 4) and has a slope of 3.
Answer
y - 4 = 3(x - 2)
y + 2 = 3(x + 4)
y + 4 = 3(x + 2)
y - 2 = 3(x - 4)
...?
The correct equation for the line that passes through the point (2, 4) with a slope of 3 is 'y - 4 = 3(x - 2)' using the point-slope form of a linear equation.
The equation that represents the line passing through the point (2, 4) with a slope of 3 is y - 4 = 3(x - 2). To find the equation of a line given a point and a slope, we use the point-slope form of a linear equation, which is y - y1 = m(x - x1), where (x1, y1) is the point the line passes through and m is the slope of the line.
Since the line must pass through (2, 4) and the slope (m) is 3, we plug these values into the point-slope form to get the correct equation.
Write three ratios equal to 7/35? A 1/7, 2/14, 3/21 B 5/7, 10/7, 15/7 C 7/35, 7/40, 7/45 D 1/5, 2/10, 3/15 I think it is C or D.
Answer:
[tex]\frac{1}{5} ;\frac{2}{10} ;\frac{3}{15}[/tex]
Step-by-step explanation:
To find the three ratios we only have to find the most simple ratio of [tex]\frac{7}{35}[/tex], and then find the other ratios that are equal to it.
So, [tex]\frac{7}{35} = \frac{1}{5}[/tex]
Also, [tex]\frac{1}{5} =\frac{2}{10}[/tex], by multiplying by two each part of the fraction.
Similarly, [tex]\frac{3}{15} = \frac{1}{5}[/tex], by multiplying by three.
Therefore, comparing all these ratios, all are the same, they are equal to [tex]\frac{1}{5}[/tex]. So, the option that correctly has these choices is D.
Solve: 3x-3y=3
y=-5x-17
The simultaneous equations 3x-3y=3 and y=-5x-17 can be solved using substitution, resulting in the solution x = -8/3 and y = -11/3.
To solve the simultaneous equations 3x-3y=3 and y=-5x-17, we can use substitution or elimination. Substitution is straightforward since we already have y expressed in terms of x in the second equation. We can substitute y=-5x-17 into the first equation:
3x - 3(-5x - 17) = 33x + 15x + 51 = 318x = -48x = -48 / 18x = -8/3Now, plug x back into y=-5x-17 to find y:
y = -5(-8/3) - 17y = 40/3 - 17y = 40/3 - 51/3y = -11/3The solution to the system of equations is x = -8/3 and y = -11/3.

At which angle will the hexagon rotate onto itself?
Answer:
The correct answer is: 60°
Step-by-step explanation:
Rotational symmetry is a type of symmetry, in which an object returns back to its original shape after rotation at an angle of 360°/n about a fixed point.
A hexagon is a regular polygon that has six edges and vertices. It has six internal angles, 120° each.
Since there are 6 equal edges, therefore, the hexagon will rotate onto itself after every rotation at an angle of: 360°/n = 360°/6 = 60°

The price of a pair of shoes is $52. The price is 15% lower than last week. What was the price of the shoes last week? Round your answer to the nearest cent. Enter your answer in the box. $
The original price of the shoes can be found by dividing the current price, $52, by 0.85, which yields an original price of approximately $61.18.
The current price of a pair of shoes is $52, which is 15% lower than it was last week. To find the original price, you can set up an equation where the original price minus 15% of the original price equals the current price of $52.
Let x represent the original price. The equation is then x - 0.15x = $52. Simplify this to 0.85x = $52. Divide both sides by 0.85 to solve for x.
x = $52 / 0.85
x = $61.18
Therefore, the price of the shoes last week was approximately $61.18.

7 × 30 = 7 × ___ tens
7 × 30 = 7 × 3 tens.
To solve 7 × 30 in terms of tens, we first observe that 30 can be written as 3 tens since 30 equals 3 × 10.
Therefore:
7 × 30 can be rewritten as 7 × (3 × 10), which simplifies to 7 × 3 tens.
So, 7 × 30 = 7 × 3 tens.

If f(x) and f^-1(x) are inverse functions of each other and f(x)=2x+5, what is f^-1(8)
Answer:
[tex]\text{The value of }f^{-1}(8)\text{ is }\frac{3}{2}[/tex]
Step-by-step explanation:
Given the function
[tex]f(x)=2x+5[/tex]
[tex]\text{we have to find the value of }f^{-1}(8)[/tex]
First we have to find the inverse
Step 1: Put f(x)=y, the equation becomes
[tex]y=2x+5[/tex]
Step 2: Replace x to y and y to x, we get
[tex]x=2y+5[/tex]
Step 3: Solve for y and then replace it with [tex]f^{-1}x[/tex]
[tex]x-5=2y[/tex]
[tex]y=\frac{x-5}{2}[/tex]
[tex]f^{-1}(x)=\frac{x-5}{2}[/tex]
Now substitute x=8, we get
[tex]f^{-1}(8)=\frac{8-5}{2}=\frac{3}{2}[/tex]
[tex]\text{hence, the value of }f^{-1}(8)\text{ is }\frac{3}{2}[/tex]
The recipe calls for 1 egg, which makes 8 slices of pumpkin pie. how many eggs would be needed to make 56 slices of pumpkin pie ?
To find the number of eggs needed for 56 slices of pumpkin pie when the recipe calls for 1 egg for 8 slices, simply set up a proportion and solve. In this case, you would need 7 eggs for 56 slices of pie.
To determine how many eggs are needed to make 56 slices of pumpkin pie, we use a proportion. Given that 1 egg makes 8 slices of pie, we set up the proportion as follows:
1 egg / 8 slices = x eggs / 56 slicesSolving for x, which represents the number of eggs needed for 56 slices, we get that x = 7 eggs.
y is directly proportional to x^2. It is known that y=10 for a particular value of x. Find the value of y when the value of x is halved
...?
If y is directly proportional to x^2, when x is halved, y becomes 0.25 times its original value. Given the original value of y is 10, when x is halved, the new y is 2.5.
Explanation:When we say that y is directly proportional to x^2, it means there exists a constant of proportionality (let's call this 'k') such that the equation y = k*(x^2) always holds. From the problem, we know that y=10 for a certain x, let's square this x sometimes referred as x2 (we could say [tex]x2 = (x^1.5)^2).[/tex]
If x is halved, the new x which we can call [tex]x1 = 0.5*x2[/tex], then substitute x1 in the equation of direct proportion we get [tex]y1 = k*(0.5 *2)^2 = y*0.25[/tex], this is because (0.5)^2 is 0.25. So, the new y when x is halved (y1) will be 0.25 as much as the original y. Therefore, if your initial y was 10, your new y would be y1 = 10*0.25 which equals 2.5.

Simplify i³⁸. [i=√(-1)]
The 38th power, [tex]i^{38[/tex] simplifies to -1.
To simplify [tex]\( i^{38 \),[/tex] you can start by recognizing the pattern that powers of i repeat every four terms. This means that [tex]\( i^{4\),[/tex] equals 1, [tex]\( i^{8 \),[/tex] also equals 1, and so on. Therefore, [tex]\( i^{38 \),[/tex]can be simplified as follows:
[tex]\[ i^{38} = i^{4 \cdot 9 + 2} \][/tex]
Since [tex]\( i^4 \)[/tex] is equal to 1, we have:
[tex]\[ i^{38} = (i^4)^9 \cdot i^2 = 1^9 \cdot (-1) = -1 \][/tex]
So,[tex]\( i^{38} \)[/tex] simplifies to -1.

A new game is being constructed where the game board is going to have 8 rows with 10 spaces in each row. What is the smallest game board that can be made?
Answer: There can be made 40 smallest game boards.
Step-by-step explanation:
Since we have given that
Number of rows = 8
Number of spaces in each row = 10
we need to find the smallest game board that can be made.
As we know that For Smallest we always find "L.C.M" because L.C.M. stands for least common multiple.
So, L.C.M. of 8 and 10 = 40
Hence, there can be made 40 smallest game boards.
